[0009] One embodiment of the packaging structure of the present invention will be described with reference to a packaging structure HK including a box 91 and a tray 92 housed in the box 91.

[0010] (Box 91) First, the box 91 will be described with reference to Figs. 1 and 2. Fig. 1 is a plan view showing a box-body expansion material 91t, which is an expansion member of the box 91 provided in the packaging structure HK of one embodiment of the present invention. Fig. 2 is a perspective view showing the box 91, seen from the upper left diagonal rear side. For convenience of explanation, the top, bottom, left, right, front and back directions are defined by arrows in Fig. 2. The left-right direction is the width direction, and is also referred to as the first direction. The up-down direction is also referred to as the second direction perpendicular to the first direction. The box-body expansion material 91t is formed of, for example, coated cardboard.

[0011] As shown in Figs. 1 and 2, the box body 91 is a hanging box and is formed in the shape of a so-called caramel box. That is, the box body expansion material 91t is formed with the back plate 11, the left side plate 12, the front plate 13, the right side plate 14, the top plate 15, the bottom plate 16, the flaps 12a, 12b, 14a, 14b, the margin plate 11a, the insert plate 15a, and the insert plate 16a. The box body expansion material 91t is also formed with the hook back plate 171 and the hook front plate 172 that can be folded back and stacked as the hook plate 17 for hanging. The hook back plate 171 and the hook front plate 172 are formed with the hook holes 171a and 172a that become openings of the same shape when stacked. Each part of the box body expansion material 91t is connected via the folding parts (folding parts LN1 to LN13) so as to be able to be folded. In Fig. 1, the folding parts are indicated by dashed lines.

[0012] The box-body unfoldable material 91t can be assembled into a box-shaped box 91 by mountain-folding the folding portions LN1 to LN13 and gluing the adhesive plate 11a to the right side plate 14. The box body 91 has an opening 91E formed by opening the hook plate 17 and the top plate 15 outward, and an inner space 91V, which is a rectangular parallelepiped space with an inner height H, an inner width W, and an inner depth L, is opened.

[0013] (Tray 92) Next, the tray 92 removably accommodated in the box body 91 will be described with reference to Figs. 3 to 5. Fig. 3 is a plan view showing a tray unfolding member 92t which is an unfolding member of the tray 92 provided in the packaging structure HK. Fig. 4 is a perspective view showing the tray 92 as seen from the diagonal rear side at the upper left. Fig. 5 is a perspective view showing a method of accommodating the first article 81 in the first accommodation section SB1 of the tray 92 as seen from the diagonal front at the upper left. In Fig. 3, the folding portion is indicated by a dashed line.

[0014] 3 and 4, the tray 92 has a front panel 21, a first side panel 22, a back panel 23, an inner panel 24, a second side panel 25, a first tongue panel 26, and a second tongue panel 27. In this example, the first side panel 22 is on the left side, the second side panel 25 is on the right side, the first tongue panel 26 is on the upper side, and the second tongue panel 27 is on the lower side. The tray expansion material 92t, which is the expansion material of the tray 92, is formed of, for example, 0.5 mm thick coated cardboard. The dimensions of the tray 92 are, for example, a width W92 in the left-right direction of the outer dimension of the front panel 21 of 62 mm, and a length L92 in the up-down direction of 98 mm.

[0015] The detailed shape of the tray 92 will be described with reference to Fig. 3 which shows the tray expansion member 92t. In the center of the front panel 21, round corner holes 213 are formed in the areas corresponding to the four corners of a vertically long rectangle, and a first storage section SB1 is formed whose four sides can be folded starting from the corner holes 213.

[0016] In detail, the first storage section SB1 is a section that becomes a recess when the tray 92 is three-dimensionalized and stores the first item 81, and is formed to correspond to the size of the first item 81 and to provide a slight tight fit so that the first item 81 does not come off under its own weight. The first storage section SB1 has a pair of insertion pieces 211 (211a, 211b) formed at the upper and lower ends and a pair of bent pieces 212 (212a, 212b) formed along the longitudinal direction.

[0017] The first side plate 22, which is connected to the left edge of the front plate 21 at a folding portion LN22, has an extending wall 22a formed in the center in the up-down direction, which extends leftward.

[0018] The back plate 23 is connected to the left edge of the first side plate 22 by folding parts LN28 and LN29, and has a hole 23a and a pair of insertion holes 23b (23b1, 23b2) spaced apart vertically across the hole 23a at the center. In addition, locking cutouts 23c (23c1, 23c2) are formed on the upper and lower edges of the back plate 23, respectively. The locking cutouts 23c are formed in a shape that is wider on the back side than the opening width of the edge, and can lock bases 261 and 271 (see FIG. 4) described later.

[0019] An insertion hole 24a is formed in the vertical center of the edge of the inner plate 24 that is connected to the back plate 23 via the folded portion LN30.

[0020] A second side panel 25 is connected to the right edge of the front panel 21 via a folding portion LN21. The second side panel 25 is formed with an insertion flap 25a at the vertical center, which is connected to the folding portion LN211 and protrudes to the right, and a pair of extending walls 25b (251, 252) that are spaced apart vertically across the insertion flap 25a and extend to the right without a folding portion.

[0021] A first tongue plate 26 is formed in the left-right center of the upper edge of the front plate 21, connecting via a folded portion LN26 and extending upward. A second tongue plate 27 is formed in the left-right center of the lower edge of the front plate 21, connecting via a folded portion LN27 and extending downward. The first tongue plate 26 and the second tongue plate 27 are symmetrical from top to bottom, so the first tongue plate 26 will be described in detail below.

[0022] The first tongue plate 26 has a base 261 connected to the front plate 21 via a folding portion LN26, and a tip portion 262 connected to the tip side of the base 261. The base 261 and the tip portion 262 are in a straight line and can be folded at folding portions LN261, LN262 that are spaced apart from each other on the left and right, and the portion between the folding portions LN261 and LN262 is a finger hook portion 26a that is a portion cut into a flat U-shape that convex upward.

[0023] As a result, when tip portion 262 is folded relative to base portion 261 at folding portions LN261, LN262, finger hook portion 26a has its U-shaped bottom side portion protruding as an extension portion on the same plane as base portion 261 (see FIG. 4). As a result, finger hook portion 26a can be pinched by fingers F1, F2 or hooked by finger F2 as shown in FIG. 10, and functions as a finger hook for pulling out tray 92.

[0024] In the first tongue plate 26, the base portion 261 has a pair of cutouts 26d that extend downward from the roots of the left and right edges and are cut downward a distance L26 from the upper edge portion 21a of the front plate 21. As a result, the base portion 261 is folded at a folding portion LN23 that connects the tip portions of the pair of cutouts 26d. The distance L26 is, for example, about 2 mm.

[0025] The second tongue plate 27 has finger hook portions 27a, a base 271, a tip 272, folding portions LN271, LN272, and notches 27d which correspond respectively to the finger hook portions 26a, base 261, tip 262, folding portions LN261, LN262, and notches 26d of the first tongue plate 26.

[0026] The tray unfolding material 92t is folded at a plurality of folds and assembled three-dimensionally to form a tray 92 having a rectangular cross-sectional shape in a sleeve shape. Specifically, the folds LN22, LN28, LN29, LN30, and LN31 of the tray unfolding material 92t are each folded at a right angle. Then, the insertion flap 25a is folded at the fold LN211 and inserted into the insertion hole 24a of the inner plate 24 and locked. As a result, a thin, flat, cylindrical sleeve shape is formed in the front-back direction as shown in FIG. 4, and the sleeve shape is maintained. That is, the tray 92 is in a sleeve shape in which the front plate 21 and the back plate 23, which have the largest area, face each other. Hereinafter, the front plate 21 is also referred to as the first plate 21, and the back plate 23 is also referred to as the second plate 23.

[0027] Next, the insertion pieces 211a, 211b of the first storage section SB1 are mountain-folded at the folding portions LN251, LN252, and inserted into the insertion holes 23b1, 23b2 of the back plate 23, respectively, and locked. In addition, the folded pieces 212a, 212b are mountain-folded at approximately right angles at the folding portions LN241, LN242. As a result, as shown in FIG. 5, the first storage section SB1, which is a recess carved toward the back, is formed and maintained in the center of the front plate 21. The first item 81 is stored in the first storage section SB1 (see arrow DR1). The first item 81 is, for example, a USB memory.

[0028] The first tongue plate 26 and the second tongue plate 27 are folded and erected at the first folding portions LN26, LN27. The erected first tongue plate 26 and the second tongue plate 28 have a length that extends beyond the back plate 23. The first tongue plate 26 and the second tongue plate 27 can be maintained in an erect state by fitting their respective bases 261, 271 into the locking cutouts 23c1, 23c2 of the back plate 23, as shown in FIG.

[0029] 4, in the tray 92, the extending wall 22a of the first side plate 22 and a pair of extending walls 251, 252 of the second side plate 25 extend toward the rear perpendicular to the front plate 21. That is, in the tray 92, the extending walls 22a, 251, 252 extend toward the opposite side to the front plate 21. In addition, the insertion pieces 211a, 211b protrude toward the rear from the insertion holes 23b1, 23b2 of the rear plate 23.

[0030] The second storage section SB2 is a rectangular parallelepiped space 92V that is flat in the front-rear direction and has a bottom surface in the area corresponding to the back plate 23 and a height HS from the tip of the insertion pieces 211a, 211b to the tip of the extension wall 22a and the extension walls 251, 252. The second storage section SB2 is a flat space suitable for storing thin items such as documents.

[0031] In this example, as shown in Fig. 6, a second object 82, which is roughly the same size as the back plate 23 and has a thickness at least less than the height HS, can be accommodated so as to rest on the tip of the insertion pieces 211a, 211b. The second object 82 is, for example, a photo card package in which a photo card is packaged in an envelope-shaped package. Of course, if the second object has a shape that does not interfere with the insertion pieces 211a, 211b, or if it can be placed in a position that does not interfere, it can be accommodated in the second accommodation section SB2 as long as its thickness is within the height from the back plate 23 to the tip of the extension walls 251, 252.

[0032] In the tray 92, a distance H921 in the front-rear direction from the front surface of the front panel 21 to the tip of the extending wall 22a is equal to a distance H922 in the front-rear direction to the tips of the extending walls 251, 252. The distance H921 is, for example, about 17 mm. The distances H921, H922 are set to be equal to or slightly smaller than the inside height H of the box body 91. The width W92, which is the outer dimension in the left-right direction of the tray 92, is set to be equal to or slightly smaller than the inside width W of the box body 91. The length L92 of the tray 92 is set to be approximately equal to or slightly smaller than the inside depth L of the box body 91.

[0033] This allows the tray 92 to be stored with almost no play in the inner space 91V of the box 91. Of course, as shown in Fig. 7, the tray 92 can be stored in the inner space V91 through the opening 91E of the box 91 with the first item 81 and the second item 82 stored in the first storage section SB1 and the second storage section SB2, respectively. Hereinafter, the box 91 containing the tray 92 storing the first item 81 and the second item 82 will be referred to as a package HT.

[0034] The orientation of the tray 92 when inserted into the box 91 may be such that the first tongue plate 26 is at the front or the second tongue plate 27 is at the front. In FIG. 7, the second tongue plate 27 is shown at the front.

[0035] Next, the package HT will be described with reference to Fig. 8 to Fig. 10. Fig. 8 is a horizontal cross-sectional view of the package HT, corresponding to the position S8-S8 of the tray 92 in Fig. 6, Fig. 9 is a vertical cross-sectional view at the center position in the left-right direction of the package HT, and Fig. 10 is a vertical cross-sectional view showing the state where the tray 92 has been pulled out partway from the state shown in Fig. 9 of the package HT.

[0036] 8 and 9, in the first storage section SB1, the movement of the first article 81 in the up-down direction is restricted by the insertion pieces 211a and 211b, the movement in the left-right direction is restricted by the bending pieces 212a and 212b, and the movement in the front-to-back direction is restricted by the front plate 13 of the box 91 and the back plate 23 of the tray 92. As a result, in the package HT, the first article 81 is stored in the first storage section SB1 without any play.

[0037] In the second storage section SB2, the second article 82 is restricted in its left-right movement by the extension walls 251, 252 and the extension wall 22a. In the inner space 91V, the first tongue plate 26 and the second tongue plate 27 are bent in a dog-leg shape (L-shape) at the folding parts LN261, LN262 and the folding parts LN271, LN272, which are the second folding parts, and the tip parts 262 and 272 are abutted against the inner surface 11b of the back plate 11 of the box body 91 and pressed forward. The tip parts 262, 272 are inclined and abut against the upper edge part 82a and the lower edge part 82b of the second article 82, respectively, and press them forward. Therefore, the second article 82 is restricted in its rearward and up-down movement by the tip parts 262, 272, and its forward movement is restricted by the insertion pieces 211a, 211b. As a result, the second item 82 in the package HT is accommodated in the second accommodation section SB2 without any rattle.

[0038] When removing the first item 81 and the second item 82 from the package HT, as shown in FIG. 10, the hook plate 17 of the box body 91 is folded backwards and spread out, and the top plate 15 is folded forwards and spread out to form an opening 91E. Next, the finger grip 26a is pinched with the fingers F1 and F2, and the first tongue plate 26 is pulled outward from the opening 91E to pull out the tray 92 (see arrow DR3).

[0039] As a result, the first tongue plate 26 is released from pressing against the second article 82, but the second tongue plate 27 slides on the inner surface 11b of the back plate 11 while being pressed by the back plate 11 until the tray 92 is completely removed from the inner space 91V of the box body 91. In other words, the second article 82 is substantially held by the package HT until the tray 92 is completely pulled out of the box body 91, and will not naturally come off the tray 92.

[0040] On the other hand, the first item 81 is stored in the first storage section SB1 by an engagement that does not allow it to come off under its own weight, so even if the tray 92 is pulled out and the first storage section SB1 is completely exposed from the box body 91, the first item 81 will not naturally come off the tray 92, but will be held in the tray 92 until it is intentionally removed by the user.

[0041] In this way, with the packaging body HT and packaging structure HK, both the first item 81 and the second item 82 can be removed from the box 91 together with the tray 92. Also, the first item 81 and the second item 82 can be removed independently from the tray 92. Also, there is no restriction on the order in which the first item 81 and the second item 82 are removed from the packaging body HT. This makes it easy to remove the stored items from the packaging body HT and packaging structure HK.

[0042] In the packaging body HT and the packaging structure HK, when the box body 91 is opened (to form an opening 91E) and the first tongue plate 26 is pulled out, the second article 82 can be picked up with fingers or the like and pulled out. In other words, the second article 82 can be intentionally removed without pulling out the tray 92, which also makes it easy to remove the article.

[0043] In the packaging body HT and the packaging structure HK, the orientation in which the tray 92 is inserted into the box 91 is not limited, and repackaging work is therefore easy.

[0044] Because the first tongue plate 26 and the second tongue plate 27 have the notches 26d and 27d formed therein, the folding positions are located inward from the upper and lower ends of the front plate 21. Therefore, even if the vertical length of the second article 82 is slightly shorter than the distance L26, which is the length of the tray 92, the upper and lower edges of the second article 82 are firmly pressed against each other by the first tongue plate 26 and the second tongue plate 27 in the package HT. This prevents the second article 82 from rattling inside the package HT even if the vertical length varies, improving the packaging quality.

[0045] In addition, in the packaging body HT and packaging structure HK, the tip portions 262 and 272 of the first tongue plate 26 and the second tongue plate 27 abut against the inner surface 11b of the box body 91 and incline inward, thereby pressing the second article 82 toward the back plate 23 of the tray 92, and maintaining the state in which the first tongue plate 26 and the second tongue plate 27 abut against the inner surface 11b of the box body 91. This creates a space between the second article 82 and the inner surface 11b of the box body 91, and the second article 82 is held without being pressed by the inner surface 11b. This allows the tray 92 to be inserted into and removed from the box body 91 without damaging the surface of the second article 82.

[0046] The embodiment described above in detail is not limited to the configuration, and may be modified without departing from the spirit and scope of the present invention.

[0047] The material of the box 91 and the tray 92 is not limited to coated cardboard, and may be corrugated cardboard. The first item 81 and the second item 82 are not limited to the above-mentioned USB memory and photo card package. The box 91 does not have to be a hanging type. [Explanation of symbols]
